Im really new to having Betta so please excuse my lack of knowledge.
I've had my first one [Flake] for almost a year now, without any problems. About 5 days ago I got my second one [Ollie] and put them both in one of those double tanks with the split down the middle.
I got Ollie because he looked healthy, and was extremely active at the shop, and when I got him home. He was then ok for about a day but in the last day or 2 all he does is float in the corner of the tank and blow bubbles, usually kinda on his side almost. & he will hardly eat anything. He still has a nice flared tail and everything.
Is there something I should be concerned about? Or is any of it normal behaviour? Also, my original one, Flake, wont stop darting around since I got Ollie, whereas he was just really lazy beforehand. Is that normal or a concern also?
